SPECIFICATION forming part of Letters Patent No. 667,706, dated February12, 1901. Application led March 17, lQO. Serial No. 91104- (NO IDOClel-lTo all whom it may concern/.-

Beit known that I, MARTIN JEWELL, a citizen of the United States,residing at Morrisons Corner, in the county of Ken nebec and State ofMaine, have invented a new and useful Mowing-Machine, of which thefollowing is a specification.

My invention relates to harvesters, and more particularly tomowing-machines; and it has for one of its objects to provide a machincwith areciprocatory table or platform which is operated by a zigzag orwaved wheel and is connected with two levers in such a manner that thelevers are simultaneously moved in opposite directions, thereby drivingthe sickles which are connected with said levers.

Another object of my invention is to so conn ect the cutter-bar with theframe that it may be adjusted at any desired angle relatively to theground over which it is passing and to permit it to follow the differentinclinations of the surface Without varying its adjustment.

A still further object of my invention is to so connect the tongue withthe raising and lowering mechanism of the cutter-bar that the rearwardmovement ofthe tongue in backing or turning the machine willautomatically lift the cutter-bar from the ground, and thereby renderthe operation of the machine much easier, and also avoid the necessityof the 0perator lifting the bar.

lVit-h these objects in view my invention consists in the improvedconstruction and novel arrangement of the parts of a machine, as will behereinafter more fully set forth.

In the accompanying drawings, in which the same reference-numeralsindicate corresponding parts in each of the views in which they occur,Figure l is a top plan4 view of a machine embodying my invention. Fig. 2is a side view of the same. Fig. 3 is a longitudinal sectional View.Fig. 4 is an enlarged sectional detail view showing the construction andmanner of operating the vibrating table. Fig. 5 is a similar viewshowing the manner of throwing the machine out of gear. Fig. 6 is adetail view of the universal joint and means for adjusting the positionof the Cutter-bar. Fig. 7 is a broken detail View of the rear end of thetongue, and Fig. Sis a longitudinal sectional view of the same.

Referring more particularly to the drawings, l indicates the frame of myimproved harvester, which may be of any desired form and construction,although I prefer to provide the rear ends of the two main side pieces 22 with suitable bearings for engaging loosely with the axle 3 of themachine. Rigidly secured to the axle between the side pieces is a zigzagwheel, the forward portion of the periphery of which passes down througha recess or notch 5 in the rear edge of a laterally-reciprocating table6, which is suitably mounted upon the side pieces 2 2 in such a manneras to be moved back and forth with but little friction or resistance.

Pivotally and detachably secured at their outer ends to the ends of thetable 6 are two brace-levers 7,the inner ends of which are provided withantifriction-rollers 8 in position to engage with the opposite sides ofthe wheel 4. A link 9 is connected at its ends to the inner ends of thelever 7 and at its center is detachably secured to a vertical standard10, the lower end of which is preferably reduced and shouldered, so asto rest upon the top of the table,when thelowerend projects through aperforation ll therein. The length of the braces isr such that normallythey will occupy an inclined position relatively to their point ofcontact with the wheel, so that when the wheel is revolving between themthe one that is under the inclined portion of the wheel will liesubstantially parallel with the face of the table, while the other oneoccupies its elevated position; but as soon as the apex of the wave hasbeen passed the two levers Will change positions relatively to the topof the table, and thereby permit the waved portion of the wheel to drivethe table back and forth without the usual binding or friction resultantfrom the ordinary construction. When it is desired to throw the machineout of gear, one or both of the latches l2 at the pivotal point of thebrace-levers with the table is thrown back far enough to permit of thewithdrawal of the bolt 13 and the disengagement of the end of the leverand the table. The standard l0 is then withdrawn from the opening ll andthe antifrictiou wheels 0r IOO rollers 8 are removed from engagementwith the sides of the wheel 4.

Owing to the looseness of the joints of the parts and the slightmovement necessary to disengage the rollers from the wheel after thestandard has been unseated it is not absolutely necessary to remove bothlatches, although it may be done, if desired.

Pivotally secured above and below the table 6, by means of pivots 14 and15, respectively, are two levers 14E and 15, the outer ends of which areconnected with two sickle-bars 16 by means of pitmen 17 in the usualmanner. The inner end of one of the levers, preferably the upper one, ispivotally secured to the reciprocatingr table near its rear edge, andthe intermediate portion of the other or lower lever is pivotallysecured to the table near its forward edge. The inner end of the lowerlever is pivotally secured to the crosspiece 18, (shown in dotted linesin Fig. 1,) near the rear edge of the table and the intermediate portionof the upper lever is pivotally secured to the cross-piece 19 in frontof the table. The outer ends of the two levers are supported bycross-bars 20 and 21, respectively. In this manner it is evident thatwhen the table is moved in one direction one of the levers will bethrown in one direction and the other one in the opposite direction,thereby causing the outer ends of the levers to simultaneously move inoppositedirections. As the cutter-bars are thus sim ultaneously drawn inopposite directions it is evident that they will have the usual cuttingcapacity when driven with half the usual velocity, thereby permitting ofa comparativelyslow movement being given to the reciprocating table withequal effectiveness at the cutters.

The shoe 22 of the cutter-bar, which may be of any ordinaryconstruction, is connected with the frame 1 by means of a suitable linkor arm 23, which is pivotally secured thereto at one end and connectedto the frame at the other end by a universal joint. rThis joint ispreferably formed from a T-bolt, which passes through an eye in the endof one of the side pieces 2 of the frame and has one end of the T formedor provided with an extension 25, which is adapted to engage with asuitable rack 26 to hold the parts in their position after they havebeen adjusted to cause the cutting portion of the cutter-bar to stand atthe proper angle or inclination relatively to the surface of the groundover which it is passing to properly cut the grain. The rear end of theshoe is connected with the rear portion of the frame upon the axle bymeans of a rod or bar 27, which is pivotally secured at each end, so asto permit of the shoe and bar having a free vertical movement, butpreventing its being drawn or forced backward by the resistance to thecutters from the grain.

For the purpose of permitting the backward movement of the tongue toraise the sicklebar from ed the ground, and thereby making the backingor turning of the machine very much easier than is possible with the barupon the ground, I provide an auxiliary lifting mechanism which willoperate independently of the usual raising mechanism 28. This auxiliaryraising mechanism consists of a le- Ver 29, which is pivotally securedupon the pivotal bolt 30 of the ordinary raising mechanism and isconnected with the shoe of the machine at one end by means of aconnector, as a chain 31, and with the tongue of the machine at itsother end by means of the link 32. The tongue is supported upon themachine so as to be movable longitudinally within lside flanges 33, andhas a bolt 34, projecting from its under side down through slot 35 inthe bottom of the frame intermediate the anges A bar 36 is rigidlysecured to the under side of the tongue and has its ends provided withcurves 37, one of which engages with the rear of the frame when thetongue is moved forward to draw the machine and the other one engageswith the front of the frame and limits the backward movement of thetongue when the machine is being backed. The top of the tongue isprovided with a laterally-extending bracket 38, to which the upper endof the link 32 is secured and by means of which movement is transmittedfrom the tongue to the cutter-bar through the chain 31 and link 32 andthe lever 29. The bracket 38 is located forward of the rear end of thelever 29, so that when the tongue is in its forward position the link 32will be inclined forward and the rear end of the lever will be held atat its highest point. As soon, however, as the tongue begins to movebackward, the link will be moved more nearly into a vertical position,thereby forcing the rear end of the lever downward and the forward end,which is connected with the shoe of the machine, upward. The doubletree39 for drawing the machine forward is pivotally secured to a draft-bar40, which is loosely mounted underneath the tongue in the usual loop orbracket 4:1. One end of the bar is connected with the shoe 22 by meansof a chain 42, and a rod 43 is pivotally secured at its ends to the.other end of the bar 40 and to the tongue, respectively. In this mannera portion of thedraft is exerted directly upon the shoe, therebyovercoming the usual side draft to a considerable extent, and alsolessening the pressure of the shoe upon the ground.

As above described, it will be seen that my invention covers a machinethat is absolutely free from gear-wheels and other complicated partsfound in many machines and that the motion is transmitted from thedrivingwheels to the cutter with the least possible waste or loss ofenergy, thereby making the machine of exceedingly light operation. Incase of any of the parts becoming broken or disarranged they can beeasily replaced or restored, and the original cost of the machine can bereduced to a minimum. In addition to this the cutter-bar is quickly andpermanently adjusted and will operate in any pos- IOO llO

sible position in which it may be thrown, and the bar can be manually orautomatically raised from the ground in backing the machine or turningit, thereby rendering it very desirable in that particular.

Although I have shown what I consider to be the most desirable form forconstructing a machine embodying my invention, yet I reserve to myselfthe right to make -such changes and alterations therein as will comewithin the scope of my invention.

Having thus fully described myinvention, what I claim as new, and desireto secure-by Letters Patent, is-
